Thanks for this. Sadly it looks like using xml just does’t work. I can’t get my main agent to switch to CSV as this looks like it might solve the problem, as he only works in XML. I’ve been back to WP All import team but so far it doesn’t look like a solution can be found.
I’ll post here again if I find a solution to this, as I suspect I won’t be the only one who has to work with XML and can’t make the all import plugin work with this theme.
